Are there too many availability options for today’s network workloads?

Following last week’s blog post on determining whether or not every server should be made virtual, a similar argument can be made regarding all of the availability solutions available for today’s systems.

Historically, I’ve found the best availability for mission-critical applications to come from a mix of the right tools. This could be utilizing DNS CNAME records for database moves or failovers, when used in conjunction with database clustering and log shipping or replication. Databases and DNS entries are among the more critical components of an application, but there are plenty of other solutions to deliver availability to workloads.
